Ezekiel 40:9-11

9Then measured he the porch of the gate, eight cubits; and the posts thereof, two cubits; and the porch of the gate was inward.

10And the little chambers of the gate eastward were three on this side, and three on that side; they three were of one measure: and the posts had one measure on this side and on that side.

11And he measured the breadth of the entry of the gate, ten cubits; and the length of the gate, thirteen cubits.
